When you start a new project you need some defined initial file structure and package.json with bunch of dev dependencies.
You can avoid to handle with it manually using this project stub.
$ git clone https://github.com/html-toolkit/project-stub.git my-new-project && cd my-new-project
$ npm install
After package manager install all dependencies you could start:
$ npm start
This will turn on grunt watch and grunt server tasks.
